401 Unauthorized on Publish

I am trying to create a new package for an older version of Castle.Windsor that is not already in the Nuget repository. I'm getting an 401 Unauthorized though. Is this because I'm not the owner of the original Castle.Windsor package? Would I
just have to rename the package? Is there an easy way to "shelve" the package and allow the original owners to verify it and publish it?
